| Abstract: | The electrodeposition of zinc-nickle alloy was obtained on a copper cathode of 1×1cm2. The deposited alloys are quantitatively analyzed by atomic absorption spectrometry. The morphology of the deposits was observed
by means of scanning electron microscopy (SEM). We observed that the electrodeposition of zinc-nickle alloy is an anomalous
codeposition. The catalytic effects of SCN” on the electrochemical behavior of Ni deposition and hydrogen discharge are obvious.
SEM analysis shows that the surface morphology of the coating appears to be more compact and homogeneous with the increase
of SCN” concentration.
